' To all whom it may concern:

, Be it known that we, STANLEY R. Throws and HARRY D. HUGHES, citizens of the United States, residing at Benton, and liytle,

'to dispensethe-liquid therefrom in predetermined quantities and thereby avoid the necessity of emptying the contents of the Another object is to provide a pump of this character which is comparatively simple in construction, easy to manufacture and edective in carrying out the purposes for which it is designed. I v

The inventive idea involved is capable of receiving a variety of mechanical expres' sions one of which, fortthe purpose of illustrating the invention, isshown in the accompanying'drawings, wherein Figure l is a side elevation of the pump showing the same attached to a barrel.

Fig. 2 is a fragmentary vertical longitudinal section.

Fig. 3 is a top plan view.

Fig. d is a similar view with the top portion of the frame removed and showing the gearing for operating the rack member and registers.

It, is customary, in dispensing oils and other liquids shipped in barrels to pour the liquids from the barrels into suitable containers such as tanks before dispensing the same. This procedure has been found inconvenient and expensive and owing to the lossv of: the liquids and time involved in emptying the same. a

The present invention, a preterred -form or which is illustrated in the accompanying drawings is designed to overcomethe above objection and to this end, use 18 preferably made of a pump cylinder ltlhawnga de-' tachable hopper bottom ll which temnates in a restricted tube 12 adapted to be extended through'the top of a barrel 1:? to

a point adjacent the bottom thereof. The lower end of the tube 21 is provided with a valve seat ltincluding a spider 15 in which the stem 16 of the vertical movable valve 17 is'mounted, said valve being adapted to open and close topermit the liquid in the barrel to be drawninto the tube 12 and retained therein.

Means are provided for -supporting the pump upon the top of the barrel and comprises a plurality of supporting arms 18 disposed radially with respect to the tube 12 and having their inner ends pivotally connected, by pins 19, to the collar 20 secured to the tube 12 adjacent the bottom 11 by means of the set screw 21. The outer end of each of the arms18 is provided with the clamping jaws 22 connected by the adjusting bolt 23 employed to adjust one of the jaws relative to the other whereby to securelyclamp the same into engagement with the rim of the barrel.

The upper end of the cylinder 10 is prei erably provided with a removable top 24 having a central opening 25 therein throughwhich the piston plunger or rod 26 extends and mounted upon the top 24 is a stufing box 27 in which the plunger 26 is movable. The top 24: further carries a faucet 28 through which the liquid in the cylinder is dispensed in a manner to appear in the .course of the description. I

The'lower end of the plunger 26 is detachably mounted in the spider-29 of the valved piston of plunger 30 having a central valve seat engaged by the vertical movable valve32. lt will be apparent from the foregoing description taken in connection with the drawings that when the piston 30 is moved upwardly in the cylinder 10 the liquid above said piston will retain said valve 32 in closed position and said liquid will be forced upwardly throughthe faucet 28. During said upward movement of the piston the suction created thereby will open.

the valve 17 at the lower end of the tube 12 and thus draw the liquid in the barrel upwardly through said tube and into the cylinder 10 beneath the piston 30. When the said piston starts its downward movementv the pressure beneath the same will open the valve 32, permitting the liquid to pass the upper part or the cylinder above said piston and at the same time said pressure will close the valve 17 and thus prevent more of the liquid from the barrel entering ltltl said tube until the piston again starts its upward movement. In this manner a predetermined amounttof liquid (the capacity of the cylinder) may be dispensed through the faucet 28. l

The mechanism for reciprocating the rod 26 and consequently the valve 30 preferably brace having the angular extensions 41 and 42 for engaging the rack bar and rod respectively. frame 43 has its lower ends secured to the sides of the cylinder 10 and extends above the top thereof and is provided with vertically disposed plates 44 and a removable top 45 forming a bearing in which the rod 26 reciprocates. A shaft 46 is mounted between the plates 44 and is provided thereon. with the large and small gears 47 and 48, the former engaging another small gear 49 while the latter engages the teeth of the rack bar 39. The gear 49 is supported upon a shaft50 mounted between the plates 44 and having secured to one end thereof the operating handle 21 adapted to be rotated in both directions to reciprocate the valve 30. v

It is further proposed, in connection with the present invention, to register the total number of gallons of liquid dispensed by the pump and also register the number of gallons dispensed at one time and, for this purpose, there are provided the registers 52 and 53 for indicating such registrations, re spectively, said registers being of any well known type and are therefore only shown conventionally in the accompanying drawings. The register 52 is operated-through a projection or pin 56 carried upon the lower end of the rack bar 39 so that each time said rack bar is raised the arm will be oscillated toregister the contents of the cylinder 10.- a

What is claimed is 7 A pump for attachment to a barrel comprising a cylinder, a frame sustained from the cylinder, a piston in the cylinder having a rod extending exteriorly thereof, a rack bar connected at its upper end with the rod and disposed with its lower end portion in direct slidable contact with the exterior of the cylinder, a pinion supported in the frame, operatively engaged with the rack bar and having a manually operable means for reversely rotating it, a suction tube depending from the cylinder and means carried by the suction tube at the base of the cylinder for engagement with the upper edge of the barrel.

In testimony whereof, we aflix our signatures in the presence of two witnesses.
